Procedure for the realization of a container and container obtained by this procedure

ABSTRACT

The procedure in accordance with the present invention comprises the following procedural steps: as the basic container form, an external contour parallel to the container support surface is realized and consists of two by two straight line pairs with each two pairs being opposed on an axis and two straight lines of a pair intersecting at the same point the axis with which they are associated and both the axes are mutually perpendicular with at least one of the two axes being a symmetry axis and mutually opposed straight line pairs enclosing the same angle with this angle remaining unchanged from the bottom upward and the mutually opposed straight line pairs involve in the case of an extension beyond the contour a parallelogram; each straight line pair is moved along the vertical axis with the movement being able to take place even on the horizontal axis with which it is associated but with at least one straight line pair changing its position on the horizontal axis along the vertical axis; and in the presence of four straight line pairs in the contour forming an octagon converted into a hexagon by movement of the straight line pairs on the vertical axis in the case where there is a single symmetry axis and a straight line pair or two opposed straight lines disappear and in the case where both a straight line pair and also two opposed straight lines disappear forming a rhombus when there are two symmetry axes with two opposed straight line pairs being able to disappear and thus forming a parallelogram.

The present invention relates to a procedure for the realization of a container and a container obtained by this procedure in accordance with the classifying part of claims 1 and 4.

Containers of known type are realized by molding, drawing, employing a tool with removal of material et cetera. In all these containers, either there must be a particular shape or the forming takes place by means of tools or even by hand. In the case of these containers they are first of all jugs, pitchers, cups, glasses, bottles or even plates if the vertical axis is quite short.

In the production of containers of this type there is thus the difficulty of working, in the case of mass production, with economical molds, i.e. molds that can be realized rapidly in accordance with a specific program. This also applies to the control of tools, if they are used, which must be controlled for example by a CCN machine.

The general purpose of the present invention is to remedy the above-mentioned shortcomings by making available a procedure in the case where a container might be formed in accordance with a particular program and the container might be obtained in a repeatable manner with great precision in accordance with this procedure.

This purposed is achieved by a procedure for the realization of containers in accordance with the characterizing parts of claim 1 and a container in accordance with the characterizing part of claim 4.

As the basic form of a container, an external contour is realized parallel to the supporting surface and consists of two by two pairs of straight lines. Two pairs of straight lines are opposed on an axis. Both the straight lines of a pair intersect the same point of the axis with which they are associated. Both pairs of straight lines mutually opposed along the height namely the vertical axis enclose the same angle. Both the axes are mutually perpendicular. At least one of both the axes is a symmetry axis. If the second axis is not a symmetry axis, each of the straight line pairs of arranged thereon consists of straight lines of different length. In the case of an extension beyond the contour both the pairs of mutually opposed straight lines form a parallelogram.

If all four pair of straight lines participate in the formation of the contour then an octagon is formed. All the straight line pairs are moved along a vertical axes. They can also be moved onto the horizontal axis with which they are associated. But at least one straight line pair must change its position on the horizontal axis along the vertical axis. Thus the axis sections enclosed by the contour change their relationship of length along the vertical axis.

The straight line length relationships also change. This applies until (in the presence of only one symmetry axis) opposite straight lines (which are associated with the axis) or a straight line pair (associated with the symmetry axis) have disappeared, that is they are no longer present as contour for the container. In this case a hexagon is formed. If two opposing straight lines and also a straight line pair disappear, a rhombus is formed.

If two opposing straight line pairs disappear (in case of two symmetry axes) a parallelogram is formed.

If the straight line pairs which disappeared reappear as a higher or lower contour, the angle enclosed thereby can be chosen new. This now remains newly constant until the straight line pair no longer intersects the contour with the other straight lines.

In one embodiment the second axis, perpendicular to the first symmetry axis, is a symmetry axis.

In one variant, an arc extends along part or all of the straight lines, for example an arc of a circle, ellipse, parabola or hyperbola and remains congruent with the displacement of the straight line pairs along the vertical axis.

To obtain different contour shapes, either another pair of straight lines or other series of straight lines can be applied on the straight lines. On it or them can again be different types of arcs which remain congruent in the movement along the vertical axis. The convexity of the arcs can be directed inwardly or outwardly.

In another variant, one of the axes is not a symmetry axis but an axis moved away therefrom. With this displacement of the axis it is possible to obtain an essentially trochoidal shape with extension of arcs on the straight lines. This is suitable then by way of example for the upper edge of a jug or pitcher lip.

One embodiment particularly suitable for plates and glasses calls for contours in the case of which, with both of the terminal points limiting the contour of a pair of straight lines, an overturning axis extends. The triangle formed by the overturning axis and the point of intersection of both the straight lines of a pair is overturned upward or downward along the overturning axis with the angle forming this triangle with the horizontal remaining constant in shifting along the vertical axis. This embodiment is only possible if both the opposite straight lines pairs are overturned and there is a symmetry axis between both the straight line pairs.

Cups, glasses and goblets as well as drinking glasses can be realized in the following embodiment: the bottom of the container consists of a parallelogram i.e. two symmetry axes as well as two opposed straight line pairs. The straight line pairs are now displaced along the vertical axis so that both of the two other straight line pairs participate in the formation of the contour. Further details and characteristics are set forth in the claims and the description given below of preferred embodiments with reference to the figures of the annexed drawings:

FIG. 1 shows an external contour suited to a basic shape viewed from above for the container;

FIG. 2 shows an external contour suitable for a cup seen from above;

FIG. 3 shows an external contour suitable for a jug or pitcher seen from above;

FIG. 4 shows an external contour suitable for a plate seen from above;

FIG. 5 shows an external contour suitable for a goblet seen from above; and

FIG. 6 shows an external contour viewed from above for any container, for example a flagon.

With reference to the figures, a container in accordance with the present invention is indicated as a whole by reference numbers 1 to 6. The shape of the container is formed in the cross section by two mutually perpendicular axes 2 and 3.

If both the symmetry axes are fixed axes, FIG. 1 applies. On each axis 2 and 3, two straight line pairs 4, 4′ and 5, 5′, as well as 6, 6′ and 7, 7′, are mutually opposed. The terminal points 8, 9, 10 and 11 and 12, 13, 14 and 15 of the straight lines are the symmetry axes on one side and a straight line of the other pair on the other side.

FIG. 6 shows on the left and right sides different views of a vessel on the vertical axis. On the left axis, the axis 3 is shown as a symmetry axis and on the right side as axis 3 (hence not a symmetry axis) . On each axis 2 and 3, two straight line pairs 28, 28′ and 29, 29′; and 30, 30′ and 31, 31′ are opposed. The terminal points 32, 34 define the symmetry axis 2, the terminal point 33 is on the symmetry axis 3, and the terminal point 35 is on the axis 3. The terminal points 36, 37, 38 and 30 form the straight lines of different pairs.

The mutually opposed straight line pairs enclose the same angle along the vertical axis. This angle must not require 180°.

The cross section varies at different heights of the vessel as follows: both the straight line pairs move on the axis 2 and 3 towards the exterior or the interior in such a manner that the length relationship of the enclosed axis sections varies along the vertical axis.

In the same manner, the length relationship of both the straight line pairs varies. If both axes are symmetry axes (FIG. 1) then this can go until two of the four straight line pairs intersect on the respective symmetry axis within the contour, as shown by the straight line pairs 4.1, 4′.1 and 5.1, 5′.1 in one position and by the straight line pairs 6.1, 6′.1 and 7.1, 7′.1, and the other straight line pairs disappear. Thus a parallelogram is formed. But this cannot be the case on the entire height of the vessel because the other straight line pair must appear lower again.

Now if an axis is a symmetry axis (FIG. 6), in moving the axis 3 further from the center, a straight line pair on the symmetry becomes still larger (shown on the right side from the straight line 29′), the other becomes still smaller (straight line 28′). Of the straight line pairs on the axis one straight line becomes still larger (straight line 31) and the other still smaller (straight line 31′). The axis 3 can be moved away as far as possible away from the center until a straight line pair or two mutually opposed straight lines disappear. Thus a hexagon is formed. If both a straight line pair and also two opposed straight lines disappear, a rhombus is formed.

If one (in the case of only one symmetry axis) or two (in the case of two symmetry axes) of the four network pairs disappear and appear again higher or lower on the vessel, then at this point the angle, to be enclosed, can be defined new, likewise the straight lines or arcs applied to them. Otherwise this angle remains unchanged along the entire height of the vessel.

The arcs, applied to the straight lines, are always congruent along the vertical axis, i.e. the tangents at the ends of the arcs are always mutually parallel from the bottom to the top. Exceptions: straight line pairs and therewith the arcs extending thereon disappear and reappear higher or lower on the vessel. The arcs newly apparent with the straight line pairs can be newly defined. These may be parts of circles, ellipses, parabolas and hyperbolas.

FIG. 2 shows the embodiments that are suitable for a cup. In front of the symmetry axis 2 extend the arcs 16, 16′ (bottom of vessel) or the series of straight lines 17, 17′ (upper edge). The length proportions of symmetry axes 1 and 2 enclosed by the contour vary between 17/17 and 17′/17′. The arc 16 is congruent with the arc 16′ and the series of straight lines 17 is congruent with the series or straight lines 17′.

In the case of a first variant for an external contour suitable for a jug or a pitcher, one or both the symmetry axes (in this case, number 3) loses its function but the terminal point of the straight line pairs 19/19′ and 20/20′ remains as axis 18. The axis 18 is formed by parallel movement of the symmetry axis 3. The axis 18 can be moved as far as possible in one direction until a pair of straight lines on the symmetry axis or a straight line of both the pairs has disappeared on the axis 18. A hexagon is formed. If both a straight line pair and two opposed straight lines disappear, a rhombus is formed. But not all of the vessel must be made up of a rhombus or a rhombus with its arcs.

In the case of an external contour of a second variant suited to plates or to a drinking glass, not all four of the straight line pairs are on the horizontal plane but only still two 21, 21′ as well as 22, 22′ which are opposed to the pairs of straight lines 21.1, 21′.1, as well as 22.1, 22′.1. Both of the other pairs are on two planes intersecting the horizontal plane parallel to the one belonging to the symmetry axis. The overturning axes 30 are among the straight lines between the points of intersection 21/24 22/24′, 21′/23 and 22′/23′, 21.1/24.1 and 22.1/24′.1, 21′1/23.1 and 22′.1/23′.1. Both of the overturned planes together with the horizontal plane make up an isosceles triangle.

An external contour suitable for a goblet constitutes the form shown in FIG. 5. In the figure, to the right of the symmetry axis 2, 25 indicates the contour of the upper edge, 26 to the left of the symmetry axis 2 indicates the contour at any point between the bottom and the upper edge, and 27 indicates the bottom.

Further changes and variants are possible without abandoning the protective scope of the invention. Different combinations of the different variants described are certainly necessary.

In place of the straight line pair on the symmetry axis, part of a cylinder is shown. The cylinder can converge conically or present an inclined axis or in place of the circular perimeter there can be shown an ellipse or a parabola or hyperbola which are put together at the ‘reversed’ ends. The symmetry axis is still kept.

In the second variant, in which all four pairs of straight lines are no longer on the horizontal plane, there can be inserted in place of the cylinder even a piece without horizontal curvature.

The second straight line pair can be appended to any point of the cylinder (or of the part which can be used in its stead).
